Elastic elasticsearch-9.1.5-linux-x86_64.tar.gz installation file issue

HI Team,

We are trying to install Elasticsearch 9.1.5 version on oel7 and jdk”21.0.7",

while extracting the file, it is giving old date, could you please check and suggest if anything can be checked from ourend.

tar: elasticsearch-9.1.5/jdk/legal: implausibly old time stamp 1969-12-31 19:00:00
tar: elasticsearch-9.1.5/jdk: implausibly old time stamp 1969-12-31 19:00:00
tar: elasticsearch-9.1.5: implausibly old time stamp 1969-12-31 19:00:00

Interesting catch, and welcome to the community.

The 1969-12-31 vs 1970-01-01 thing is just a few hours diff due to different timezone, but this seems to have been the case for a while now, 9.0.6 and 9.1.3 resp in 9.x series.

Hi Team,

PLease update on this topic

Oddly enough I don’t get this warning (Ubuntu 25.04) even though the timestamps might be considered “implausibly old”.

Anyway these are just warnings, you can either ignore them or suppress them with --warning=no-timestamp if they bother you.
